What are the examples of physical and logical files?
Physical files include things like paper documents, hard drives, USB drives, and CDs. Logical files include databases, spreadsheets, and email accounts.
How many logical drives can be created on a fat drive?
When you partition a hard drive into two or more partitions (storage areas) those extra drives are called logical drives. So you can have 2 or 3 or more logical drives on one physical hard drive. It varies.
What separates the physical aspects of data storage from the logical aspects of data representation?
A schema separates the physical aspect of data storagefrom the logical aspects of data representation.

What is raid technology used for?
As a rule, the most common RAID levels in use today are:No RAID - logical data volumes exist within single physical driveRAID 0 - logical data volumes striped across multiple physical drives with no parity/data protection. Common, but not necessarily a good idea (backup is important here).RAID 1 - logical data volumes mirrored, bit-for-bit, between two physical drives (in come implementations, additional mirror drives can be created)RAID 5 - logical data volumes striped across multiple drives with parity/data protection generated and distributed among all drives in the RAID set.Three notes come to mind:Depending on implementation, RAID devices appear as a logical (or physical) drive to the OS or application. Software RAID, configurable in utilities such as in Windows Disk Manager or MDADM (Linux) works just below the operating system, providing a representation of a virtual physical disk to the operating system.Sometimes, RAID levels are combined, such as RAID 0+1 (striped, then mirrored) or RAID 1+0/10 (mirrored, then striped).As drives and RAID sets get larger (2-3 TB+), the time to recalculate/recover data for a failed physical drive becomes prohibitive, both in downtime/degraded operation and vulnerability to data loss from an additional failure.A number of new technologies, as well modifications to classic RAID, are being explored to address shortcoming 3.
What is the name of the table at the beginning of a hard drive that tells where logical drives?
Partitioning Table
A physical hard drive that has 2 or more drive letters?
It probably has a partition, which is a way of separating a physical drive into 2 or more logical drives. This is useful is you want to install 2 operating systems, or if you want your operating system on one drive and your data on the other.
